Blood is the source of human life. The human body continuously provides oxygen, nutrients, moisture, growth factors, antibodies and various active enzymes to all tissues and cells in the body through blood, and excretes metabolites in the body through blood circulation. If the physiological function of blood is abnormal and unclean, like a river full of silt, the metabolism of human body will be disordered, and various organs of human body will be diseased, which is particularly easy to cause cardiovascular and cerebrovascular diseases (such as hypertension, hyperlipidemia and hyperviscosity). ).

Only people with healthy blood can be healthy. If all nutrition and energy sources are problematic, can we still believe that we are a healthy person? There is a famous saying in Chinese medicine since ancient times: "Qi is the handsome of blood, and blood is the mother of qi. The disease comes from the blood, and the disease is treated from the blood. " Therefore, no matter from the point of view of treatment or health care of cardiovascular and cerebrovascular diseases, we should improve and restore the physiological function of blood, reduce the blood viscosity, promote blood circulation and remove blood stasis, make blood gas smooth, make blood healthy, and make all tissues and cells get rid of the old and welcome the new. This is the fundamental place to protect cardiovascular and cerebrovascular health.

The product principle of Kangxing semiconductor laser low-frequency therapeutic instrument is to use the biological stimulation of laser energy to act on nasal mucosa and improve blood rheology and microcirculation. Stimulating sympathetic nerve and parasympathetic nerve in nasal cavity by laser energy with wavelength of 650 nm makes the blood vessels of nasal mucosa contract and expand, which reflexively improves intracranial blood circulation and systemic blood circulation, thus helping to reduce blood pressure, blood viscosity and blood lipid.
